Answer:
Change in potential energy is 700.7 J.
Explanation:
Given:
Mass of the object is,
kg
Height to which the object is raised above his head,
m
Acceleration due to gravity is,
m/s²
We know that for a mass
raised to a height
, the change in potential energy is given as:
, where, 
Now, plug in the given values and solve.

Therefore, the change in the potential energy is 700.7 J.
C. newtons/meter
Explanation:
The unit of spring constant K is newtons/meter.
The spring constant is also known as the stiffness.
F = k e
F is the force
k is the spring constant
e is the extension.
The unit of F is newtons
e is meters
Therefore, k becomes newtons/meter
- Stiffness is the resistance to stretch of a body.
